Intercropping is defined as growing two or more crops together,that is, in proximity and on the same piece of land during thesame growing season (Willey, 1979). Intercropping increases spa-tial and temporal exploitation of water through increased rootdensity and differences in rooting patterns of species (depth, widthand length), but only if complimentary interaction between thecomponent crops is exhibited. Under intercrop systems there is alsoearly attainment of full canopy cover and this reduces soil evapo-ration earlier in the growing season (Coll et al., 2012; Ofori et al.,2014; Walker and Ogindo, 2003). Zougmore et al. (2000) observeda 30% reduction in runoff when sorghum was intercropped withcowpea (Vigna unguiculata Walp). It is possible that intercroppingsorghum with either cowpea or bottle gourd (Lagenaria siceraria(Molina) Standl.) can improve water management in rainfed crop-ping systems. However, these assumptions still need to be testedrigorously to make meaningful recommendations.
